PNEUMATIC STACKER.

lEGIElGATlON forming part of Letters Patent No. 688,897, dated December 17, 1901.

Application filed June 13, 1901.

To aZZ whom it may concern:

Be it known that I, JOHN GEORGE TAYLOR, a subject of His Majestythe King of Great Britain, residing at Dnnrea, county of Rock Lake, Province of Manitoba, Canada, have invented certain new and useful Improvements in Pneumatic Stackers; and. I do herebyde- Clare that the followingis a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in pneumatic stackers for grain-separators and threshing-machines; and the object in view is primarily to save the chaif and some of the tailings from passing off with the straw, thus making the chaff, 850., available for use during the winter-time'as feed for the farmers live stock.

A further object is to arrange the parts in a way to discharge the chaff along with the straw, if desired, upon the straw-pile, and, furthermore, to simplify and cheapen the con strnction and toinsure efficiency in operation.

With these ends in View the invention consists in the novel construction, combination, and arrangement of parts, which will be hereinafter fully described and claimed.

In the drawings hereto annexed, forming a part of this specification, Figure 1 is a plan view of a pneumatic stacker constructed in accordance with my invention. Fig. 2 is a sectional plan View, the plane of the section being indicated by the dotted line 2 2 on Fig. 3 and the flexible chafi-disoharging tube being shown in its horizontal and laterally-deflected positions by full and dotted lines, respectively. Fig. 3 is an enlarged vertical section through the rear portion of a grain-separator or threshing-machine and representing my improved stacker mechanism in sectional elevation, together with the chaff delivery tube connected operatively with the primary stacker tube. Fig. 4; is a sectional view through a universal joint adapted to couple the flexible chaff-delivery tube to the windtrunk of the fan associated therewith. Fig.

5 is a detail sectional View illustrating the cut-ofit between the primary stacker-tube and a part of the chalf-delivery tube.

The same numerals of reference denote like parts in each of the figures of the drawings.

Serial No. 64,371. (No model.)

are ordinary in the art, and no novelty therefor is claimed in this application, the same being shown herein merely to enable others skilled in the art to understand the invention.

The rear portion 9 of the machine-frame supports a fan-casing 10, and said framework is also equipped with suitable shaft-bearings 11, in which is journaled the fan-shaft 12, the same carrying a rotary fan or blower 13, whereby the fan may be rotated within the casing. For the purpose of distinguishing this fan from another fan which is associated with the primary stacker-tube I will on proper occasionsrefer to the fan 13 as the chafftnbe fan. The shaft 12 is provided with two pulleys 14 15, around the latter of which passes a belt 16, that is adapted to be driven.

from any suitable working part of the grainseparator or threshing-machine. The other pulley 14 has an endless belt 18 fitted thereto and arranged to drive the stacker-tube fan 19, the same to be hereinafter more fully described. A wind-trunk 20 has its lower portion operatively connected with the fan-casing 10, while its upper portion is enlarged and curved so as to fit beneath that section of the machine-casing 5 which incloses the endless straw-carrier 8, all as more clearly shown by Fig. 3. This wind-trunk thus has an enlarged tapering mouth arranged to partially inclose the rear open portion of the grainseparator, and the chaff and short straws which are delivered by the grain-pan 7 and are blown from the cleaning-shoe 6 by the ordinary shoe-fan are adapted to be delivered into this wind-trunk 20. Furthermore, the wind-trunk tapers toward its rearportion, as clearly shown by Figs. 2 and 3, in order that it may have the chafE-delivery-tube 21 connected thereto, said tube 21 consisting of a series of sections 21, 21", and 21. These series of sections are connected flexibly together by the pivotal joints 22 of a character Well understood by those skilled in the art, and the innermost section 21 of this chaffdelivery tube is loosely fitted to the delivery end of the wind-trunk 20, as shown more particularly by Fig. at. The flexible construction of the chaff-delivery tube permits it to be shifted laterally in a horizontal plane and either to the right or left, so that the outer end of this chaff-delivery tube may be arranged to deposit the chaff directly into a chad-house, a bin, or any other place of storage. This adaptation of the chaff-delivery tube is a very advantageous feature of my invention, because it permits the chaff to be delivered from the separator directly into the place of storage without requiring the attention or services of an operator, and the chaff is saved by discharging it from the separator independently of the straw, so that the chaff may be utilized during the winter season as feed for the farmers stock.

I do not limit myself to any particular or detailed construction of the chaff-delivery tube; but this'tube should be of such a nature that it may be swung laterally in a horizontal plane, as described, and it should also be capable of a flexion movement in a vertical plane, to the end that the extremity of the tube may be connected operatively with the primary stacker-tube 23.

I. will now proceed to describe one embodiment of means by which the tube 21 may be swung upwardly to the position shown by Fig. 3.

2 L designates a carrier-ring having the arms 25, which are bolted or otherwise fastened to the wind-trunk 20 in a manner to sustain the carrier-ring 2 1 firmly in position around the wink-trunk and the member 21 of the flexible tube 21. This carrier-ring has the slots .26, in which are loosely fitted the frictionrollers 27, that are mounted at the outer ends of the plates 28, the latter being firmly secured to the member 21 of said flexible tube. It is evident that the rollers 27, which are supported by the plates 28 on the flexible,

tube, may be made to travel in the slots 26 of the carrier-ring for the purpose of giving a semirotary movement to the tube member 21 of the flexible tube in order that the latter may be shifted to the position indicated by Fig. 3, wherein the pivots 22 between the tube-sections permit said flexible tube to be raised or lowered. Under this adaptation of the flexible tube the outer member 21 thereof may be brought into operative relation to a short fixed nozzle 29, which is provided on the under side of the stacker-tube 23 and is arranged to inclose an opening 30, provided in the under side thereof. A coupling band or sleeve 31 is arranged to inclose the adjacent ends of the nozzle 29 and the outer member21 of the tube, said coupling-band being loosely connected, as at 32, to the nozzle and having a detachable fastener 33 connected with the tube member 21 of the chaff-delivery tube.

It is evident that the chaif blown through the wind-trunk 20 by the action of the fan 13 may be" carried by the flexible tube 21 into the stacker-tube 23 when said parts are adcease"? justed as shown by Fig. 3; but the fastener 33 may be disengaged in order to release the flexible tube, and the latter may then be lowered and given a semiturn on the wind-trunk in order to restore the chaff-delivery tube to either of the positions indicated by full and dotted lines in Fig. 2. When the flexible tube 21 is disconnected from the stacker-tube 23, the opening 30 in the latter is closed by means of a cut-off 3.4., the latter being shown in Fig. 5 as a slidable damper; but of course the style of cut-ofi may be changed. I

36 designates a hood which has a swiveled or pivotal connection at 37 to the rear portion of the casing 5, wherebythe endless straw carrier 8 is arranged to deliver the straw di rectly to the hood. This hood is also adapted to swing horizontally in order to change the place of discharge of the straw, and to the outer end of the hood is connected a stacker= tube 23 by means of the hinge-joint 38. This hinge is located at the upper side of the hood in order that the stacker-tube may be folded over and upon the separator; but the lower part of the stacker-tube has a lip 39, which is arranged to lap under the hood. (See Fig. 3.)

The blast-fan 19 has its shaft 19 supported in suitable hangers 40, which are secured to the machine-casing, and around this blastfan 19 is arranged the casing 41, which is ar ranged to have its lower part 42 connected with the hood 36, whereby the fan 19 is adapted to be driven by the belt 18 from the fanshaft 12, and the blast of air from said fan 19 is arranged to catch the straw as it drops from the endless straw-carrier 8, so as to carry the straw through the hood 36 and the stackertube 23.

It is thought that the operation and advam tages of my invention will be readily understood from the foregoing description, taken in connection with the drawings.

Changes within the scope of the appended claims may be made in the form and proportion of some of the parts, while their essential features are retained and the spirit of the invention is embodied. Hence I do, not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.
